About this app

Have you given up every time you tried to memorize only Hiragana?

This app helps you study Japanese, from those who don't know a single character to those preparing for the JLPT exam.

It is perfectly fine to study on your own.

■ Hiragana
- Lessons are prepared so you can read, write, and listen to Hiragana.
- You can see words and pictures for each character and listen to the pronunciation.

■ JLPT N5-N1 Step-by-Step Learning
- We provide customized learning based on your target level.
- You can keep track of Japanese vocabulary, Kanji, and grammar separately.

■ Review that returns just when you might forget
- Incorrect answers appear more frequently, while well-known ones appear less often.
- It shows you in advance when and how many pages will return.
- If you enter the exam date, it sets your daily study quota based on the remaining days.

■ Practical Mock Tests
- Prepared with question types that appear on the actual exam.

■ Reports
- You can see at a glance how much you have done so far and where you have left off.

"Dandan" (だんだん) means stairs in Japanese. Let's build your Japanese skills one step at a time.

- The Japanese Language Proficiency Test (JLPT) is an exam administered by the Japan Foundation and the Japan Association for International Education.

- This app is a learning tool and is not affiliated with either organization.
